Geeklog Forums

How's everyone doin? I was wondering if I could get help in replacing the Geeklog banner on my site (the one at the top left corner) with my customized site banner. I am a total noob and just wanted to replace that with my site's name. Is there an easy way to do this?
Also I installed the Gameserver theme for my site (GL 1.3.11) and everything is fine cept the forum's color is too contrasting. The rest of the site is dark and the forum is this unreadable mess of white and brown. anyone know whats wrong?
Thanks

the header information (including the GL image reference) is located in the header.thmtl file in your layout/yourtheme/ folder... if the image you're replalce is the same dimensions you might just rename the image (located in the layout/yourtheme/images/ folder)...

the forum colors can be found in either the additionalforum.css file or in the style.css file located in the layout/yourtheme/ folder

Thanks jetshack. I'm getting the hang of it now.
I have another question. I have installed like 20 different themes for GL, and some of them dont show the 'contribute' link(which shows on theme:professional and other themes). Is there a way I can add this? and say I dont wanna call it contribute cuz it seems like im asking for a paypal donation. could i change it to sumthing like 'story submission'?

How do I change the menu?

Where can I change the text ...?
